ATTZNEY Patented Apr. 21, 1936 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to improvements in tobacco pipes. The draught or suction of such pipes is frequently impaired through the clogging which takes place at the bottom of the pipe bowl, and particularly at the junction of the bowl and the pipe stem, which clogging is due to continual accumulation of the various ingredients distilled out of the tobacco during the smoking. Those accumulated ingredients have to be frequently scraped out of the bowl, as, besides impairment of the suction, they also form hard or viscuous masses which seriously vitiate the taste of the tobacco.

The principal object of the invention is to provide a tobacco pipe with improved and eflicient means for remedying the above mentioned disadvantages, to ease the conveyance of the smoke through the pipe, and to prevent the distilled objectionable ingredients of the tobacco from reaching the smokers mouth.

Another object is to provide a tobacco pipe having simplified, inexpensive, reliable, efflcient, and improved means for retaining an absorbent material for remedying said disadvantages, and for readily, rapidly, and conveniently discarding and renewing said material.

Another object is to effect the improved distillation of objectionable ingredients from the tobacco within the pipe.

Other objects and advantages will hereinafter appear.

In the accompanying drawing,-

Figs. 1, 2, 3 are longitudinal cross-sectional elevations of tobacco pipes embodying the above referred improvements.

Fig. 4 is a plan view of a detail of the improvements shown in Fig. 3.

The pipe I, Fig. 1, comprises a tobacco bowl 36 and stem portion 31, which are attachable to and detachable from each other by means of the threaded portions shown. A tablet I2 made of suitable absorbent material and provided with passageways I4 for the smoke is located in a recess 98 formed in the underside of part 36. Said tablet is retained in place against dislocation by means of a metallic band device 91, which passes under and around the sides of the tablet, and terminals 99 of the band pass through a grate 53 and bend thereover as indicated. A chamber I is provided in the bowl-part 31 directly under the tablet I2, and the smoke filling said chamber is led to the stem 31' through a pipe IOI extending from said stem to the upper portion of said chamber, a depression I02 in the bottom of the chamber serving to collect objectionable precipitations.

In Fig. 2 is shown a spring band device I03 for retaining the tablet I2 'in the bottom of the bowl-part 30. Said band passes around the top 5. and sides of the tablet, and its terminals I04 pass through the opening 19 of the tobacco-bowl 36, under which 'theyare of the bent configuration I05 shown to lockingly remain in place. Upon destruction of the absorbent tablet I2, after it 1-0 is used up, 'thedevice I03 may be easily removed by bringing the bent springy terminal parts I05 toward each other.

According to the modification shown in Figs.

8, 4, the retaining device I06 resembles the one shown in Fig. 2, but it is made of a perforated metal sheet I01 which serves as a grate and rests upon the tablet I2, and legs I08 extending from said sheet are configurated and utilized similarly to the corresponding parts of the device shown in Fig. 2.

After considerable use of the pipe the absorbent tablet I2 may be renewed by detaching the bowlparts 36, 31 from each other, demolishing the tablet material and discarding it, and withdrawing the device 91, I03, or I01, whereupon a fresh tablet may be replaced with the retaining device restored to functioning position. As the suction at the pipe-stem 31 progresses, the smoke from the tobacco is conveyed through the passageways Id of tablet l2, which then absorbs objectionable ingredients, and then the smoke enters and fills the chamber I00, wherefrom the smoke enters the tube IOI and passes into the stem 31', as indicated by the arrows. During the 35 smoking of the pipe the solid distilled precipitates which constitute objectionable ingredients become deposited within the depression I02, from which they may be cleaned out by the smoker during renewal of the tablet I2.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:-

1. A tobacco pipe having the combination of a two-part bowl, means to attach and detach said parts, the upper of said parts having a bottom adapted to sustain the tobacco and an opening in said bottom to permit suction therethrough, an absorbent tablet located at said bottom, and an elongated metallic band embracing said tablet horizontally and vertically as a tie having its terminal protrude through said opening to secure the tablet to said upper part.

2. A tobacco pipe having the combination of a two-part bowl, means to attach and detach said parts, the upper of said parts having a bottom adapted to sustain the tobacco and an opening in said bottom to permit suction therethrough, an absorbent tablet located at said bottom, and an elongated metallic band embracing said tablet horizontally and vertically as a tie having both of its terminals protrude through said opening to secure the tablet to said upper part.

3. A tobacco pipe having the combination of a two-part bowl, means to attach and detach said parts, the upper of said parts having a bottom adapted to sustain the tobacco and a plurality of openings in said bottom to permit suction therethrough, an absorbent tablet located at said bottom, and an elongated metallic band embracing said tablet horizontally and vertically as a tie having its terminals protrude through a pair of said openings to secure the tablet to said upper part.

4. A tobacco pipe having the combination of a two-part bowl, means to attach and detach said parts, the upper of said parts having a bottom adapted to sustain the tobacco and an opening in said bottom to permit suction therethrough, an absorbent tablet located at said bottom, an elongated band embracing said tablet horizontally and vertically as a tie having its terminal protrude through said opening, and said terminal having means to lock it to said upper part.

5. A tobacco pipe having the combination of a two-part bowl, means to attach and detach said parts, the upper of said parts having a bottom adapted to sustain the tobacco and an opening in said bottom to permit suction therethrough, an absorbent tablet located over said bottom, an elongated band embracing said tablet horizontally and vertically as a tie having its terminal protrude through said opening to secure the table to said upper part, and said band having a perforated plate integral therewith disposed on top of said tablet for its protection.

6. A tobacco-pipe having the combination of a two-part bowl, means to attach and detach said parts, the upper of said parts having a bottom adapted to sustain the tobacco and an opening in said bottom to permit suction therethrough, an absorbent tablet located oversaid bottom, an elongated band embracing said tablet horizontally and vertically as a tie having its terminal protrude through said opening, and said terminal having means to lock it to said upper part.

7. A tobacco pipe having the combination of a two-part bowl, means to attach and detach said parts, the upper of said parts having a bottom adapted to sustain the tobacco and an opening in said bottom to permit suction therethrough, an absorbent tablet located underneath said bottom, an elongated band embracing said tablet horizontally and vertically as a tie having its terminal protrude through said opening, and said terminal having means to lock it to said upper part.
